GAS-LIGHTING APPARATUS.

To all whom it may concern:

Be it known that l, ROBERT M. DIXON, residing at East Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Gas-Lighting Apparatus, of which the following is a full, clear, and exact description, such as will enable others skilled in the art tc Which it appertains to make and use the same.

This invention relates to an illuminating apparatus, but more particularly it concerns features of construction of casing for a gas lamp.

@ne object of this invention is to provide a structure particularly applicable to the side Walls of a railroad car or other inclosure to be lighted.

Another object Within the purpose of this invention resides in a means for inclosing a gas lamp which will provide a superior system of ventilation, whereby the vitiated products of combustion may freely escape and fresh air be freely supplied to take the place of the same.

^inother object Within the contemplation of the invention consists in an inclosure for a gas lamp whereby access may be conveniently had to the latter in order that a proper operation of the same may be insured.

Another object is to provide a convenient means in an apparatus of the class described whereby the flow of gas may be readily controlled.

Another object is to provide a gas illuminating apparatus, which, from an operative standpoint, Will possess a high degree of efficiency and `durability in usage, and which, structurally considered, will be of the utmost simplicity consonant with the ends to be attained, being composed of but few parts, all adapted for being made at a minimum of cost and individually so formed as to be capable of being easily assembled into a neat and compact arrangement-fer accomplishing the purposes intended.

Other objects and advantages will be in part obvious and in part pointed out hereinafter.

7With these and other ends in view, this invention accordingly consists in the features of construction, combinations of parts and arrangement of elements which Will be eX- emplitied in the embodiment thereof herein- Specification of Letters Patent.

Application led February 16, 1906.

after described and the scope of the application of Which Will be indicated in the following claims.

ln order that the invention may be more fully understood and made comprehensible to others skilled in its relating arts, drawings illustrating a convenient manner of carrying out the same are appended as a partof this specification, and, While the controlling` principles of the invention may be otherwise applied by modifications falling Within the scope of the claims, the herein disclosed embodiment is that Which will ordinarily be preferable to employ in practice, and is regarded as representing substantial improvements over many of the seemingly obvious variations of the same.

in the accompanying drawings, like numerals of reference denote corresponding parts throughout all the figures, of which,

Figure l is a sectional elevation showing the general arrangement of the parts as applied to a side Wall. Fig. 2 is a horizontal section of the device set forth by F ig. l and showing certain details of construction not clearly appearing in said ligure.

ln the practical carrying out of this invention, it will be clear that various types of illuminating burners may be employed in connection therewith, but as a better distribution of light is obtained from the consumption of gas in an inverted burner, the preferred form of the latter is embodied in this exempliiication of the invention.

The burner as a Whole has been designated on the drawings by l and comprises a stop cock 2 of suitable form and construction, to which is connected, by means of an inspirater 30, the lamp or burner body 3l.. The inspirator 30 may be of any desired construction adapted to dran7 in air from the space surrounding the lamp body and inject the same, together with the gas passing through the cock 2, into a mixing chamber 32 formed in the said burner body. The nozzle 33 depending from the body 3l provides a channel through which the coinbustible mixture passes from the chamber 32 to the inverted mantle di. Surrounding the mantle is a globe 35 having an opening in the bottom thereof through Which air is admitted to the exterior of the mantle to aid in the proper combustion of the combustible mixture issuing from said nozzle Passages or channels 2S are provided in the body 81 to carry off the products of combastion, so that the inspirator will not introduce vitiated air into the mixing chamber. ln order that space may be economixed, it is preferable to arrange said stop cock in a recess or concavity 3 which is formed in the side wall of the car or otherI inclosure to be illuminated. lVhile not essential for the application of the casing around the lamp, it will be convenient in practice to provide the latter with a section l consisting of one or two thicknesses which conform in contour to said recess and closely interfit therein, being` secured in place by suitable means, such as screws or the like and being adapted to resist the passage of heat. At its upper end, such part preferably protrudes in a flange 5 which carries the roof t3 of the casing, which may be atA tached thereto by suitable screws 7' or the like. Such roof is so designed as to permit of a free discharge of the heated, vitiated products of combustion which rise through the channels 2S indicated in dotted lines in Fig. 1 provided by the lamp or burner body portion, and, to 'that end, one or more gables or escape vents S may be provided, having openings, as at 9. A subsidiary ventilator 10 may be suspended from the under surface of the roof by means of a series of posts 11 and, preferably, such subsidiary ventilator will provide a circumferential vent 12 for the outflow of part. of the gases. The lamp is so arranged as to directly underlie the aforesaid parts and discharge its waste gases toward the same. A horizontally eX- tending battle Q9 surmounts the lamp and directs the gases toward said vent.

As it is desirable to have convenient access to the burner features, the intermediate or body portion of the casing, designated by 13, will be swiveled on a suitable hinge 1l to one side of the same and, at its other side, 15, will be provided with a suitable catch, which will normally retain said intermediate portion in a closed position. r1`he said intermediate portion provides one or more` openings 16 through which the light may pass, and said openings will ordinarily be closed against the flow of air by means of a suitable window 17, which may be of any suitable, transparent material. This window 17 is shaped to present a number of faces inclined upwardly toward the wall so that the whole unit has somewhat the appearance of a pyramid. As, however, the most convenient material for the purpose is glass, and as the same is likely to crack spontaneously under the infiuence of excessive heat or jarrings, this invention proposes, as a preventive, an interposed packing-ring 18 of asbestos or other suitable material, which commonly will overlap the edges of the window which rests in suitable seats provided by the intermediate casing portion.

rThe window may be held in place through the instrumentality of clips of suitable construction, such as those shown on the draw ing and designated by 19, said clips being securely affixed to the intermediate portion, as by means of screws 2O or the like. This window is therefore enabled to be removed as an entirety, thereby greatly facilitating cleaning.

rlhe intermediate portion, which constitutes a swinging door, will, in practice, be provided with means co-acting to normally maintain the same in a closed position, and such means will usually consist of a preferred type of spring-latch, such as that designated on the drawings by 21, in which an end 22 engages within a suitable seat in the swinging door.

The stop-cock 2 will be provided with an extension handle 2", which adapts the same for being actuated very conveniently. he bottom portion of the casing is denoted by @et and provides suitable inlet orifices 25 for the inflow of fresh air. Such bottom portion will preferably be carried by suitable wings QG extending from section 4e through a suitable attachment 27.

1t will now be clear that the embodiment hereinbefore described is well adapted for attaining the objects and advantages above stated. The structure, as an entity, is particularly suitable for use in connection with the side walls of a roo-m or other inclosure and, accordingly, is well fitted for railroad purposes. Certain characteristic advantages obtain as a result of the employment. of a wall recess, as for example, economy of space and positive position. Furthermore, the construction permits of an artistic appearance and, to that end, th-e parts may be given a polygonal contour, as shown on the drawings.
